Response surfaces for parent and child accommodation and child-rated subsequent severity of symptoms in SPACE vs. CBT

	Entire sample		SPACE		CBT		Differences
Effect	Coefficient	p	Coefficient	p	Coefficient	p	Coefficient	p
Slope along x = y	0.29	.25	0.48	.41	0.51	.35	−0.02	.98
Curvature along x = y	−0.23	.01	−0.15	.41	−0.33	.02	0.18	.45
Slope along x = -y	−0.06	.81	−0.58	.40	−1.68	.02	1.10	.25
Curvature along x = -y	0.002	.93	−0.01	.87	0.08	.16	−0.09	.28

Notes. Slope along x = y refers to the slope of the line of agreement. Curvature along x = y refers to the curvature along the line of agreement. Slope along x = −y refers to the slope of the line of disagreement. Curvature along x = −y refers to the curvature along the line of disagreement. The coefficients are computed based on multilevel response surface analysis by polynomial regression models. For more details, see Nestler et al.(2019).
